Bow Bridge is a rural locality of the Shire of Denmark in the Great Southern region of Western Australia.

[3][4] Much of the locality is covered by protected areas, with the Walpole-Nornalup National Park in the west and the Quarram and Mehniup Nature Reserves in the south-west.

The Owingup Nature Reserve is only partially located within Bow Bridge, in the east, along the Kent River.

The roadhouse was established prior to 1960 and operates as a fuel station, post office, grocery store and cafe.

[6] The siding of Kent River, Quarram and Marks on the Elleker to Nornalup railway line were located in the current locality of Bow Bridge.
